Lepiota felina is generally similar to several other small to medium-sized lepiotas for which microscopic examination of the spores and structure of the cap cuticle is important for determination of species. It has a broadly convex cream-white cap with a very dark brown center, concentric zones of small brown patches, and radially arranged matted squamules at the margin. The gills are white to faintly pinkish, the cap flesh is white and non-staining, and the odor is like cedar wood or somewhat unpleasant and rubbery. The stipe is whitish to pale brownish above the ring and pinkish brown to grayish brown with zones of brownish squamules below. The ring is cuff-like and typically is adorned with brownish squamulose patches. The spores are ellipsoid to oblong and the cap cuticle is composed of tufts of long erect elements that arise from clavate cells.
